Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Dicloxacillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and leading to cell lysis. It is resistant to penicillinase-producing organisms.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
125-500 mg orally every 6 hours

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
Terminal elimination half-life: 0.6-0.8 hours in adults with normal renal function; prolonged to 1-2 hours in neonates, elderly, or severe renal impairment.
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Primarily renal: ~60-85% unchanged via glomerular filtration and tubular secretion; ~10% hepatobiliary (bile) and fecal; minor metabolism to penicilloic acid.
